He said: "When the Article 50 debate comes up, we will put forward an amendment to it, about market access and protections. We want those to be part of the negotiations.

"We are respecting the result of the referendum. It might not be the one we wanted but it's the one we've got."

He denied the amendment could delay the process and backed the right of courts to "interpret legislation and what Parliament does".

He said the reason for the amendment was that "there are those in the Tory party who want us to sever all connection with Europe, reduce corporate taxation, set up some kind of bargain basement trade agreement with the USA".

"The result would be a reduction in wages, reduction in public expenditure and ultimately a big reduction in living standards across Britain," he added.

Mr Corbyn refused to rule out demanding a second referendum on the exit terms, when they are finally negotiated.

But he said he did not agree with former Labour prime minister Tony Blair, who believes the referendum result can be reversed.
